Lag problems regarding Ship or minecart or Trident

Hello, now in the game the spawn point has changed from the northwest to the center of the block. And I have designed the farm with a similar concept to the Java version. From the picture it can be seen that the boat and trident have a lot of lag even when the Restone circuit isn't working. This causes the FPS to drop from 120 to <40, what I want to convey. I want to optimize the ship and trident so they don't take up too much work space. I would like to use the same space as a normal solid block to reduce lag. Thank you!
